The RTC test application allows you to read the current time from the RTC; set it using the system time; and read, set, and test the alarm interrupt. Syntax To display the application syntax, run: rtc_test -h Examples Test the alarm interrupt with the specified seconds: ...
The M241 Logic Controller includes an RTC to provide system date and time information, and to support related functions requiring a real-time clock. To continue keeping time when power is off, a non-rechargeable battery is required (see reference below). A battery LED on the front panel of ...
